With Japanese handset sales declining pretty much across the board (thanks, lower subsidies!), it follows logic that the government and Japanese-based handset makers would look internationally to pick up the slack. In a rather vague report, we're told that the nation is hoping to push its technologically advanced mobiles in other countries, though it'll have a tough time marketing mobile TV without sufficient infrastructure. One of the token handsets chosen to lead the parade is a Sony-made "wallet phone," which is only described as having cashless technology built in. Color us (very) mildly enthused.
